Definitions

• the present invention relates to an antiperspirant stick of the type of water-free or low-water dispersion sticks, the antiperspirant active ingredients of which are dispersed in a carrier consisting of a liquid, non-polar carrier material, setting fat or wax components and surfactants.
• water-free dispersion sticks consist of a dispersion of finely divided astringent aluminum or zirconium salts in a non-polar carrier liquid solidified by gel formers or wax-like fat components.
• non-polar carrier liquids e.g. Hydrocarbons or silicone oils, preferably those with boiling points below 200 ° C or with a certain volatility, e.g. cyclic siloxanes (cyclomethicones) and their mixtures with skin-softening oil components are used.
• Such anhydrous dispersion sticks sometimes have the disadvantage that the antiperspirant effect of the astringent salts does not start quickly and intensely enough.
• the addition of surfactants has already made the stick mass more hydrophilic and also improved the washability of the residues from the skin or clothing.
• US Pat. No. 4,151,272 describes antiperspirant sticks which contain up to 5% by weight of a fatty alcohol polyglycol ether.
• EP 491 843 B1 antiperspirant stick compositions are known which contain an adduct of 10 moles of propylene oxide with butanediol to reduce the Weissel effect.

• the astringent salts should be finely divided, their average particle size should be less than 100 ⁇ m and preferably less than 50 ⁇ m.
• An aluminum hydroxychloride of the formula Al 2 (OH) Cl * 2-3 H 2 O is particularly preferably present in an amount of 15-25% by weight as the astringent salt.
• astringent salts are coated or impregnated with a water-soluble, nonionic surfactant.
• Alkyl (oligo) glycosides which have been applied in amounts of 0.1 to 5% by weight to the surface of the salt particles have proven to be particularly suitable surfactants for this purpose.
• Suitable as a setting fat or wax component are more or less all saturated, linear fatty acids and fatty alcohols with 14 - 22 C-atoms, triglycerides of saturated fatty acids with 14 - 22 C-atoms, saturated linear wax esters (fatty acid-fatty alcohol esters) with 28 - 44 carbon atoms or mixtures thereof.

• Suitable water-soluble surfactants are in principle all surfactants that are soluble in the system at 1% by weight at 20 ° C. and at least 1% by weight soluble in water at 20 ° C. Although the structure and ionogeneity per se are insignificant, nonionic surfactants, in particular the addition products of the ethylene oxide which are solid at normal temperature (20.degree. C.) to fat molecules with at least one alkoxylable group, seem to be particularly suitable. Such suitable surfactants are e.g.
